Vendor Central shows gross revenue minus obvious deductions but misses critical costs: allocated co-op, chargebacks, freight allowances, return costs, advertising by SKU, and proper overhead allocation.

Complete ASIN P&L includes: wholesale purchase price (COGS), inbound freight, co-op allocations (both required and incremental), all chargebacks (compliance, logistics, shortage), advertising costs by SKU, return costs and shrinkage, payment term financing costs, and allocated overhead.

Monthly minimum for comprehensive portfolio reviews. Weekly for key products and new launches. Continuous monitoring with automated alerts for products crossing profitability thresholds. Quarterly deep-dives for strategic portfolio decisions.

Options include: price increases if market allows, cost reduction (renegotiate supplier terms, optimise packaging), marketing elimination (stop promoting margin destroyers), channel reallocation (move to 3P), or discontinuation. Decision depends on strategic importance and fix feasibility.

Absolutely. Model expected profitability before launch using benchmarks from similar products, category data, and realistic cost structures. This prevents launching products that will never achieve acceptable margins.

Continuous monitoring catches fee changes immediately. Established profitability frameworks enable rapid impact analysis when Amazon changes co-op rates or introduces new fees, you immediately understand portfolio impact and can make informed pricing or cost adjustments.
